The Nature of the Transient Overvoltage Problem Overview of hazards Electrical transients in the form of voltage surges have always existed in electrical distribution systems, and prior to the implementation of Semiconductor devices, they were of minor concern. The vulnerability of semiconductors to lightning strikes was first studied by Bell Laboratories in 1961. [1] A later report tried to quantify the amount of energy certain semiconductors could absorb before they suffered latent or catastrophic damage from electrostatic discharge. [2] Despite these early warnings, industry did not begin to address the issue satisfactorily until the late 1970s. All electrical and electronic devices can be damaged by voltage transients.
